Start off by defining variables

okey (:

That they add up to 11 pounds haha

good, so x y and z add to 11, which means
x+y+z = 11

that's one equation

so x+y+z=11 :o

yes

But then we have to factor in how much they cost..

this total cost is given to be $21
so
1.5x + 3y + 1.5z = 21

so like, 1.50x+3.00y+1.50=21..

Haha Okey you already said that x.x my bad

1.50z* I meant btw haha. I get that indeed.

close, you mean to say 1.50x+3.00y+1.50z=21
but you got it

And don't forget twice the peanuts!

that's your 2nd equation

twice the peanuts as what?

it says, the recipe calls for twice as many peanuts as almonds O.o

good, so the equation for that is?

ermm.. I dunno lol.. x(times2y)+y+z=11 O.O I have no idea.

not quite

knew it was wrong x.x

Amount of peanuts = 2 times (amount of almonds)

y = 2 times x
or just
y = 2x

oh pshh I should have thought of that x.x

so you have these 3 equations
x+y+z = 11
1.5x + 3y + 1.5z = 21
y = 2x

you can use them to solve for x, y and z

I'll get you started

Lol I can't because I'm stupid, But smart people definitely can haha

so after plugging in y = 2x, you now have the new system
3x+z = 11
7.5x + 1.5z = 21

O.o That all made absolutely no sense to me but it seems to for you and that's good enough for me

where are you lost?

I did the same with 1.5x + 3y + 1.5z = 21 to get 7.5x + 1.5z = 21

oh okay ! I see now, sorry it's really late and I'm super tired :/

so you have
3x+z = 11
7.5x + 1.5z = 21
now

solve the first equation for z to get this
3x+z = 11
3x+z - 3x = 11 - 3x
z = 11 - 3x

Alrighty

oh wait, i made a variable mistake...i switched x and y
one sec

Let me fix real quick

I was thinking that haha x) ..

uhh ? your comment disappeared .. :o

sry

Solve 6y + 1.5(11 - 3y) = 21 for y

haha it's okay

Aw man I have to go to bed soon I'm dead tired x.x

What do you get when you solve that equation for y

ergh I dunno x.x I'm brain dead

Then give it a break, get some sleep and you'll tackle it in the morning

Oh no I keep losing connection >.<
